All user reviews for the Electro-Harmonix Octave Multiplexer XO

An analog octave pedal to EHX size, supplied with standard 9v in a robust metal shell. A button for the filter action on the treble, one for bass, a knob that handles the mix between the dry and wet so that actuating the switch subs or not frequency (station qux hp guitar!). Jack in, jack out and roll youth!

UTILIZATION

It's pretty simple, there is a manageable her quite easily.

SOUND QUALITY

The big worry as others have said are spurious stalls. But it gives him a dirty side that after reflection (I sold since ...), I would have kept my studio. If this is not playable live, stalls for a specific part can have a charm. The subs are mushy and the position is not sour, filters act reasonably but not folichon either. I ask to try a bass that can be correct. Otherwise I regret that ny is not an octave higher.

OVERALL OPINION

I kept it about a year, I sold it because I did not have utility in my rig, I no longer uses octaveurs available. I love its robustness and low price, I do not like instability and lack of options finally. Like many EHX I put it in the bizarre use studio effects box.

So let me explain what this pedal professes to be. It has a high filter and a bass filter. A blend knob. A sub stitch. Has a dry and wet output which is a nice feature. Basically it's a sub octaver. EHX generally makes pretty well built pedals for the price this one feels solid.

UTILIZATION

I am a collecter of odd and out there pedals which means EHX stuff it a pretty frequent staple of me. They have a lot of octavy pedals and some of them are very nice. I bought this having no real idea exactly what it should be used for. There are really two applications for this pedal. You can use it as a bass emulator or as a special effect for vocals and such.

SOUND QUALITY

I first used this as a vocal effect for electronic music projects and for that it's pretty darn good. I tried it with my guitar briefly and decided it was pretty "toylike" for anything other than bass emulation. More on that in a bit. The vocal effect is a lot like something you would hear on a daft punk or Kayne track. Some people might find it over the top but I guess it depends on the genre. Now here's where the problem lies. My friend was at my practice space messing with some of my pedals and he was trying to make his strat do a bass emulation. He switched on the sub switch and had the bass knob rolled up and there was so much bass coming out of the speaker that it blew my 2x12. Speaks for itself. Dangerous costly pedal.

OVERALL OPINION

Now let me be clear, I really liked this pedal for the crazy vocal effects. But as a bass sim it blew my speakers and didn't even sound all that great to be honest. I haven't heard of other people blowing speakers with this. Maybe I just got unlucky. I have since let go of mine because I don't need it anymore and don't want anymore blown speakers.

Octaver analog two possibilities, two of which correspond two octaves diffrent filters

UTILIZATION

Config 'so easy, no need for manual!

SOUND QUALITY

While the DSOL but no, it's not great ... I have several and that the EH is the only one who love me of ..

Frankly, its octave is difficult Grable, the SUB is a hyper-muddy and trs normal random image and sound is loud, despite a vintage grain CHARACTERISTICS (a pity that it possde a nice sound ..) but whatever the rglage the Octave multiplexer PICK UP all the time and not at all prcise ...

It is true that its design dates from the 70's, but for those who want an effective Octaver is dcevant ...
As proof, I prfre my old Boss OC2 even if it is to rpute dcrocher unexpectedly, I find it even better ... right

OVERALL OPINION

I use it for about a year, but in fact I never russi incorporate it into a component so I do not trust her ...
I also have a Boss OC2 OctaBass and EBS, the two are much more useful ..

The Vintage pedals or their equivalents rditions (in this case) are the best in the normment catgories like Fuzz / Disto / Overdrive / Chorus / Flanger / Phaser / Delay / Envelope filter ( dj which is much ...), but for the style pedals octave / Align / Pitch-Shifter, prfrez them something more modern, because it is the kind of fact that volumes and more ...

To answer the notice at the bottom, this pedal is not made to play right, but rather to the single note, it will be the trs prcise

UTILIZATION

Can be used very easy shuffled the effect + note

or only hear the effect!

SOUND QUALITY

Exeptionnel if you like vintage sounds funky

OVERALL OPINION

I bought this pedal There's about a year and have sold being a big fan of hendrix to buy the roger mayer octavia, well it's the biggest BTIS I did because I TElement will redeem the sound is pure !!!!!

Two knobs for different levels of octaves. a knob for mixing between the signal light and effect.
One In, One Out and output without the effect.

A metal case, a large button that can be crushed with the foot, which the solid.
The on / off switch is really low end, it intends to effect the engagement.
A shame but hey ...

UTILIZATION

No need for manual, I guess it's a piece the size of a blue card also ...

SOUND QUALITY

His level, when used with a low, stable is it not answer (on long notes it starts a little but good), it makes the job well.
Plus now that I think the BOSS.
Bypass the output is quite useful for attacking a distortion, it's not drool all over ...

On a guitar means more filter top, and filled out the sound.

Pushing the signal completely drown in effect gives the sound pretty cool ...

OVERALL OPINION

Cheap, its does the job pretty well. Over time, I focus more on the pedal ampeg, which sounds terribly well (it's hot, its not pick a hair ....) but terribly more expensive. (240euros)

Good buy for cheap what.

OCTAVER ANALOG

UTILIZATION

Very simple configuration

SOUND QUALITY

The sound quality is not bad, however the effect takes down all the time, impossible to make long notes etc!
short unusable.
I am a big customer EHX and there is really very bad surprise.
The pedal should not even be marketed + + +
I am surprised that no one talks about this drop!
it is frankly horrible unplayable.
I highly recommend this pedal, even a poor boss OC2 OCCAZ of 50 euros is a lot better the job.

OVERALL OPINION

I have been using the one year since it's over.
If qqu'un wants me to buy it!
I sold it on, new state, with box and goodies EHX.
I bought it from thomann without trying it because I trust EHX, big mistake on my part.
For many old EHX pedals, I do realize that the new nano and other EHX XO does not hold water!
at EHX now they are in marketing mode + + + That's it!

This pedal double the note an octave lower ...
I do not know what is the technology used, but it is not editable or rack, not noon. Not matter to me, especially with three touch buttons ...
In a form, an Out in jack, classic anything, and a second sheet to break out the effect in another amp (or sound system ...) to separate the effect of the direct signal.

UTILIZATION

Configuration is very simple: 2 filters and a High Bass filter to shape the sound of the octave added, and the Blend to mix with the direct.
Memory to 12 were half half direct signal / octave...A far right is no longer the direct signal and it seems to have a bass in his hands.
The manual is very clear but frankly, useless. Moreover, a manual starts at 2 pages not to deserve the name? There, I think there was only one.
There is a switch "sub" on / off, which I do not see the need (personally) as in off, it cuts the filter "Bass" and an octave down, I find it unfortunate, but perhaps y'en loving after all.
Ideal for use to thicken the sound a bit, add depth, or playing riffs "dubbed" super cell like a good bass player (yes it's you because of it! Hey hey!)

SOUND QUALITY

So, I'll be bothered to record ...
I use it with a Start 'and a Les Paul.
At first, I would put 10/10. It's clean, it not answer, it's great sound (pedal breathes strength too!), It manages to sculpt the sound you want depending on the game we practice and what we want him to do ...
BUT ....
(Yes, otherwise I would have put 10 and it would cost more I think ...)
BUT ....

But there's a HUGE FALL OF SIGNAL !!!!!
The volume decreases tremendously, it ruins everything, and it's unmanageable. A home to train, to mumuse, look for sound, nickel, but in game config, only worse and in groups, or alternately playing with and without octave, it is not possible. Required to trigger a boost .. So if we budget to justify buying another one, much to type in another model ... it's really unfortunate, because without this fall, it was a great product.

OVERALL OPINION

Ben ... I mean a pseudo 5/10...en big to work from home and have fun, it's super cam use but the actual game, no. Or must love a boost switch on and off each time you want to remove and the effect ... or, if you played on an entire song, well you climb your amp time of the song and after you rebaisses .. (it will be nice scales !)... I kept it very long. A friend lent me the Boss OC-2 I found a little messy, but I quickly sold my Multiplexer to buy the OC-2, much easier to manage, despite the slightly "Rrrrhhh! " And I regret it.
Too bad, because Electro-Hamonix missed a golden opportunity to sell a cheap little pedal to pump larigot ... and frankly, I am not a technician, but it's that hard to add the component that requires that the volume does not move? It's the economy that ... tee 2 francs, not even € 2 ... It's a shame, but it was great!

Octaver analog rather low, but with a lot of harmonic HF leaving.

Three pots: High filter, filter and low bleed.
A switch "sub on / off".

A footcswitch, bypass structure. LED operation (red). Standard metal housing EH. An input jack, two jack output (dry and wet).

UTILIZATION

Given the lack of buttons, the config is simple.

The manual is as usual with EH rather succinct, but it's not very serious. They state that this is an effect expected for the mono. At least one is warned ...

As with all EH effects, the battery is only accessible by unscrewing the bottom (4 screws). Not ultra convenient. But it is the 4 rubber feet that bore me to put it in my pedal board, as they raise on-the bottom of 3-4 mm can not put the velcro without turning the rubber feet. What repulses me.

The LED is highly visible. I could not test the autonomy given that I used exclusively with my pedal board power supply.

Dry output must be capable of leaving the unprocessed sound on a separate line. I confess that I've never served me.

SOUND QUALITY

I was looking for a octave-down with his dirty and deep, analog-to-the-Jack White, whatever. Well, I've found is the Octave Multiplexer.

She goes out of octaves can be very active (when you put the bleed-bottom, equivalent to a depth control for the effect). There are many strange artifacts when it grows much effect. It is true that I've watched too aps how the circuit worked, but since it is obviously a purely analog stuff (I have not seen anything that closely or remotely to a DSP / codec inside, and that's not the kind of home) I wonder if this is not some kind of monophonic synthesizer, which "scan" the frequency of the signal and re-created a pseudo-sine wave one octave below. I wonder how we could make an octave-analogue down otherwise ... In any case it would explain why the effect works well in mono, and does stuff in crados polyphonic.

Regarding the sound quality is pretty clean, or rather regular when we do not put too much effect, but then it is rather light relative to its dry. If you push, you get artifacts irregular, it is boring. There is a filter for high-frequency and one for bass frequencies. It's convenient to mitigate some of these artifacts, but it has the drawback of many filtering his total. Sub button allows you to add more octaves. The sound is even more dirty, it's cool, I like.

The biggest problem of this pedal, besides his side a bit messy, is that it greatly reduces the overall sound, and as there is no volume control ... I've found the trick, I use it routinely with a Little Big Muff. This way I can adjust the volume, and I have a good sound monstrous to many of the solo (which allows me to have a good solo sound with my Jaguar, which is not really cut out for solos, especially next to a guitar player who plays with Les Paul). With that my keyboard sound at the beginning of Space Truckin 'on Made in Japan Deep Purple. With a Telecaster it also makes good.

Incidentally, the output is separated Dry afford to make a little more advanced setups (like putting a foot on the gain on continuously wet for not having to activate every time you activate the Octave) but it's true that I have not yet exploited this feature.

Same comment as the Little Big Muff (must be valid for all EH pedals): The footswitch is very noisy, and we hear a little amp. on the other hand, this pedal adds no noise. Or at least I am not able to hear it.

OVERALL OPINION

I've had a year and I used with my band Songs on one where I'm just solo, almost, so with the Big Muff's going well. I cut and I do that the Big Muff is the chorus chords (that falls well ...). Frankly, it really adds depth to my sound, in this particular case. I intend to use it in other songs later.

It's a bit of a pedal to occasional use, even unique. Like many EH pedal, it will say, yes, probably. Still, I believe that it fulfills its function.

Analog octave pedals are not common, especially in this kind of price (Moog? Anyone?). I tried a few of Octavers digital sound and I did not really. Too cold, too ... digital and artifacts are really present. Here too I will be told. Yes, but the advantage is that its remaining analog, I do not get AD-DA conversion in my chain of effects. Which is anyway a huge advantage. And imprecise and rough side gives him a real personality.

In hindsight I do it again this election, because it really brings something unique. But it must be coupled with a gain or distortion, it is difficult to use alone.
